Set DataContext in XAML

Question

I have this simple application that adds some items to a combobox:

public partial class Window1 : Window
    {
        private ObservableCollection

        

Answer 1

Just change the Window to bind DataContext to itself:

<Window x:Class="WpfApplication2.Window1"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Window1" Height="300" Width="300"
        DataContext="{Binding RelativeSource={RelativeSource Self}}" ... />

Answer 2

I believe the DataContext in this scenario is implicit and does not have to be set since you are using the code behind. If you were using MVVM you would add a reference to that folder and class inside of you XAML markup and set the resource key equal to a value that can then be declared as the DataContext inside of a child elements DataContext property. But in your case (since you are not using MVVM) you shouldn't have to do that.
